COMBINED DOOR STOP AND LOCK.

SPEGIFEGTIOII forming part of Letters Patent No. 691,003, dated January14, 1902.. Application fled April 28, 1900- Serial I\l'o. 14,700. (Nomodel.)

To all whom tt may concern.-

Be it known that I, GEORGE I-I. SAWIN, of the city and county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in a Combined Door Stop and Lock; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being hadto the accompanying drawings, forming a partof this specification, and in which- Figure l represents a horizontalsection through a door, its jambs, and a plan of my said improved doorstop and lock, the same being combined with the door and said door inholding the door open. Fig. 2 represents,

`upon an enlarged scale, a vertical section through part of the bottomof the door with the spring-latch of the locking device attachedthereto, the same being swung up into a ver` tical position against itss\1pporting-plate,fas tened to the door, as when not in use. All thefollowing igures are also upon the same enlarged scale. Fig. 3represents a vertical section through part of the flooring, and a sideview looking in the direction of arrow ct, Fig. 4, of the door-stop andvertical holding-pin, over which the aforesaid spring-latch is tted tohold the door, as will be hereinafter described. Fig. Atisahorizontalsection through part of the bottom of the door and showing a plan of mycombined stop and lock device p in the same position as in Fig. l, andFig. 5

represents a front detached view of the springlatch of the lockingdevice.

The object of my invention is to provide a device which shall serve as astop or bumper for a door when opened and swung back, and whereby saiddoor may be locked to the floor when thus opened andswung back; and itconsists of a metal or other suitable plate adapted to be fastened tothe iioor and upon which are mounted an elastic stop or bumper and aVertical pin.

It also consists of a metal or other suitable plate adapted to besecured to the side of the bottom of a door and having pivoted thereto aspring-latch adapted to be engaged with the vertical pin on theaforesaid floor-plate, as will be hereinafter more fully set forth.

To enable others to better understand the nature and purpose of my saidinvention, I will now proceed to describe it more in detail.

In the drawings, A represents part of the floor, and B the door, towhich are respectivelysecured the metal plates C D. The plate C, whichis secured to the fioor, has mounted thereon asuitable door stop orbumper E'and also the vertical pin F. Said stop or bumper may be madeinvarious ways. In thisinstance I have shown a cylindrical-shaped studE,pro jecting up verticallyfrom the plate Gand having a vertical grooveb iu the side next to the door, in which is titted a piece of rubber cor other elastic material for the door to strike against when swungopen, as is shown in Figs. l and 'et of the drawings.

The plate D on the door has formed thereon near its hott-oni edge twoparallel verticallyarranged fiauges or ears D' D', between which litsthe base end of the latch G, being pivoted` thereto by the transversepin II. Between said latch and the plate D is fitted a :suitable springI for exerting a pressure upon the base of said latch to hold the latchin any adjusted position. Said latch is also made of the proper shape to(it over and hold on the vertical pin F, projecting up from theHoorplate C. In this instance said result is accomplished by forming ahole d transversely through the plat-e constituting the outer end of thelatch at the proper point to permit said pin F to pass up through itwhen the latch is sprung down over the pin, thereby detachably fasteningthe door to the floor-plate C, asis shown in Figs; 1 and 4. The latch isdesigned to be attached and detached to and from the pin on thefloor-plate by means of the foot of the person opening aud closing thedoor, and to facilitate said operation it is preferable to have a knob eformed on the outer end of said latch, under which the edge of the soleof the boot or shoe may be caught to raise the latch out of engagementwith said iloor holding-pin; but as it is' not an essential feature I donot limit myself thereto, neither do I limit myself to the use of thespring I or to the exact construction shown of other parts of thedevice.

My device is intended mainly for large heavy doors in public buildingsand is new so applied and its usefulness practicallyV demonstrated. Itsadvantages are ap parent without any detailed statement thereof. It maybe readily applied to any door and is easily TOO operated in locking andunlocking the door, being operated by the foot Without stooping to thefloor, as previously stated.

Having now described my invention, what I Claim therein as new, anddesire to secure by Letters Patent, is-

l. A combined door stop and lock, comprising in combination theHoor-plate provided with an elastic bumper and a holding pin orprojection; the door-plate, a latch pivoted thereto, adapted to beengaged and disengaged to and from 'the aforesaid pin or projection, anda spring for exerting a pressure upon said latch, substantially asandfor the `hole near its outer end and Whose inner end is fittedbetween said ears D D', and pivotpin H, passed transversely through saidears and latch, in combination with plate C, secured to floor A andhaving the pin F projecting vertically therefrom; the elastic bumper o,and means for holding it in position on said plate C, substantiallyasrand for the purpose set forth.

GEORGE H. SAWIN.
